CHANNEL BRICK.

Application filed December a, 192%. Serial No. eeaeea To all whom it may concern:

Be it known that l, ARTHUR HAnnoN- cover, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Channel Brick, of which the following is a description.

The channel brick which is the subject matter of this application is of the same general t pe as disclosed in my issued patents num iered 1,068,338 of July 22nd, 1913, numbered 1,311,069 of July 22nd, 1919 and numbered 1,373,238 of March 29th, 1921.

My present invention is an improved type of channel brick, and the object of the invention is to provide an improved construction of channel brick embodying a new grip for handling the bricks.

As the channel bricks are preferably less than three inches in height, it is desirable that any channels which are provided in the bricks to be used as a grip be relatively deep. In my invention these channels for gripping purposes are not only relatively deep, but the sides of the channels are so shaped that the masons thumb and fingers may be readily introduced into the channels to their bottom to obtain a good grip on the brick without danger of the mason injuring his knuckles against rough surfaces or sharp edges. Not only is the brick constructed to accomplish this most desirable result, but the brick is strong and is not unnecessarily weakened by the channels in the brick, whichpermit a mason to grip-the brick quickly without danger of injuring his fingers.

Additional objects of the invention will appear in the following specification, in which the preferred construction is disclosed,

In the drawing similar reference char acters refer to similar parts in all the views, in which 1 Figure 1 is a perspective view showing a portion of a wall constructed with my channel brick;

Fig. 2 is a perspective View showing one of the channel bricks of a size larger than the ordinary bricks shown in Figure 1; and

Fig. 3 is a fragmentary View illustrating how a mason may introduce his fingers into one of the channels in the brick By referring to the drawing it will be seen that the brick is constructed with par allel channels 5, the outer walls 6 of which are spaced from the sides 7 of the brick, these sides 7 of the brick being preferably provided with recesses 8, which assist in coating the sides 7 of the brick with plaster or stucco, as may be desired.

The inner walls'of the channels 5 are corrugated, as shown at 9, which assist a mason in obtaining a gripon the brick and which also serve as a tie for the mortar 10 with which the bricks are held together.

The outer walls of the brick are curved downwardly and inwardly, as shown, at 10, to the bottom of the inner Walls, 9. J

This curved outer wall 10 makes -.it possible for a mason to introduce his bent fingers into the channel 5, as illustrated in Figure 3 of the drawings. The width of the channel 5 at the top 11 ofthe brick is only sufficient to permit the ready introduction of the masons fingers, but the curved outer wall 10 of the channel serves to retain substantially the same width of the channels at some distance below thetop of, the brick, the width of the channels decreasing very slowly downwardly so that the masons fingers when partially closed will not ordinarily come in contact with the outer wall of the channel while the tips of the fingers are moved downwardly to engage the innerwall 9 of the brick at the bottom of the channel. It will be seen by examining Figure 3 of the drawing that while this desirable result is obtained,-that the width of the channel at the. top of the brick is not increased as would be necessary if the outer wall of the brick were straight and inclined downwardly and inwardly therefore, it will be seen that the brick is not onl constructed with a View of making it possi le for a mason to readily introduce his fingers while partially closed, into the channel, but the strength of the brick is preserved and the greatest possible-extending surface at the top of the brick is maintained. This is important as it not only preserves the strength of the brick, but it also provides the greatest possible area for supporting mortar at the top of the brick.

At the bottom of the brick there are grooves 12, which receive mortar as illustrated in Figure 1 of the drawing when the bricks are laid with mortar as a binder.

I claim:

1. A channel brick having two substant ally parallel c annels Which are relatively deep and leave only webs between the bottom of the channels and the bottom of the channel brick, corrugations on the channel brick at the inner sides of the channels, the

channel brick at the outer sides of the channels being curved downwardly and inwardly to the inner sides of the channels so that the channeh brick at the channels will be strong and the channels at their upper portions will be relatively narrow while sufficient to permit a mason to introducehis fingers while partially closed into one of the channels without striking his knuckles against the outer walls of the channels,

thecchannel brick having load-bearing portioils between and at the outer sides of the channels.

2. A channel brick having two substantially parallel channels, thechannel brick at the outer sides of the channels being curved downwardly and inwardly to the inner sides of the channels, so that the width of the channel downwardly will become less gradually which will permit a mason to introduce his fingers while partially closed into a channel and hold his fingers in this way until they are positioned to be moved against the inner wall of the brick, the channel brick having load-bearing portions between and at the outer sides of the channels. 7

3. A channel brickprovi dc'd upon one surface with a long extending grip located between parallel channels, the outer surfaces of the channels being curved upwardly and outwardly from the base of the grip to the upper surface of the brick, the upper surface of the grip being in the same plane as the upper surface of the brick, the channel brick having load-bearing portions be- '40 tween and at the outer sides of the channels,

4. A channel brick provided upon one surface with a longitudinally extending grip centrally located between parallel channels, the outer surfaces of the channels being curved upwardly and outwardly from the bottom mortar receiving channels to the uppersurface of the brick, the upper surface of the grip being in the same plane as the upper surface of the brick, theexposed sides of the brick being scored for receiving plaster, the channel brick having load-bearing portions between and at the outer sides of the channels.
